Wireless window sentinel
Date:9/5/2012

the s-net technology developed by IIS for extremely energy-efficient wireless data transmission to a base station. This can take the form of a PC, cell phone or tablet, even a room controller. "The s-net wireless sensor network is a multi-hop network where sensor nodes exchange data both with each other and with master nodes," says Taschka. Nodes have a communication range of 20 to 30 meters, which defines the maximum distance between one window and the next. Multi-hop capability means the system can cover vast areas, making it suitable for use in businesses. Installed in an office building, it could provide front-desk security staff with window status information and so do away with the need for walk-through checks. Another feature of the window sentinel is that it requires no cables or batteries. The sensor draws all the power it needs from its surroundings. The underlying technology, known among experts as "energy harvesting", enables power to be derived from ubiquitous sources such as air currents, vibrations or in this case sunlight and ambient heat.

Thermoelectric generators embedded in the window frame transform heat into power. Solar cells attached to the outer window frame also help power the 3-D sensor. "Our tests showed that this works even in north-facing windows," says Andreas Buchholz, Head of Research and Development at Seuffer.

Obviously, the system is suitable for everyday use only if all sensors function reliably. To ensure that this is the case, each chip is equipped with a coil that creates a magnetic field as soon as power is applied. If a signal is emitted, then the sensor is intact. "The window monitor is the result of a vigorous exchange of ideas we've maintained over the years with Fraunhofer researchers," says Buchholz.

The window, which includes the sensor, magnet, RF node and solar cell, is currently available as a prototype. By the end of the year it is expected to be ready for mass production. Manufacturing wi
